peptide-calculations (Python)

Unit-safe Python calculations for peptide reconstitution, concentration, dilution and molarity. The package mirrors the transparent calculation contract of the JavaScript package while keeping the Python install dependency-free.

Install and run

python -m pip install peptide-calculations
peptide-calculations reconstitution --mass 10 --target 5

The command returns JSON. For a 10 mg material and a target of 5 mg/mL, the calculated volume is 2 mL.

The Python API is also available:

from peptide_calculations import calculate_reconstitution

result = calculate_reconstitution(10, "mg", 5, "mg/mL")
assert result["volumeMl"] == 2

Use mM only when a molecular mass in daltons is supplied. Inputs are unit checked, and dilution rejects a target concentration that is not lower than the stock concentration.

For a browser-based companion, see the Péptido México reconstitution calculator. This is research-use-only software: it does not calculate a dose, recommend administration or validate a physical device or analytical method.

Development

PYTHONPATH=src python -m unittest discover -s tests -v
python -m build

The package is maintained by Péptido México, a commercial supplier of research materials. That relationship is disclosed so users can distinguish software maintenance from scientific interpretation.
